7142SA100J

Overview

The Renesas Electronics Corporation 7142SA100J is an asynchronous dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features a parallel interface with a maximum access time of 100 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate systems
• Asynchronous operation without requiring a system clock signal
• CMOS technology construction for standard TTL-compatible logic levels

Applications

• High-speed data buffering between processing units
• Cache memory implementation in embedded systems
• FIFO buffer applications in communication interfaces

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment prior to integration. Review manufacturer documentation for any product change notifications or material composition updates relevant to the specific manufacturing batch.

Selection Notes

Evaluate the 100 ns access speed against system timing requirements. Ensure the 52-PLCC footprint matches the printed circuit board layout. Verify that the 4.5V to 5.5V operating voltage aligns with the target power supply rails and environmental temperature constraints.
